用於可撓螢幕的轉軸結構與折疊式電子裝置Rotating shaft structure for flexible screen and folding electronic device

本發明是有關於一種轉軸結構，且特別是一種用於可撓螢幕的轉軸結構與折疊式電子裝置。The present invention relates to a hinge structure, and in particular to a hinge structure for a flexible screen and a foldable electronic device.

隨著科技不斷精進，採用可撓螢幕的折疊式電子裝置已逐漸成為未來的發展趨勢，而在這類裝置，例如智慧型手機或筆記型電腦，其通常是讓可撓式螢幕設置於兩機體上，且當所述兩機體藉由轉軸而相對旋轉以折疊或展開時，使該可撓螢幕能隨之在彎折狀態與展開攤平狀態之間轉換。With the continuous advancement of technology, foldable electronic devices with flexible screens have gradually become the future development trend. In such devices, such as smart phones or notebook computers, the flexible screens are usually arranged in two bodies. When the two bodies are relatively rotated by the rotating shaft to be folded or unfolded, the flexible screen can be switched between the bent state and the unfolded and flat state.

然而，由於可撓螢幕被彎折時，其彎折處存在內側、外側的周長變化，因此在進行轉軸的機構設計時便需要將所述變化列為考量，並需讓轉軸的機構得以配合所述彎折，從而避免因轉軸與可撓螢幕的轉折狀態無法相互配合，進而對可撓螢幕造成損壞。However, when the flexible screen is bent, there are changes in the circumference of the inner and outer sides of the bend. Therefore, when designing the shaft mechanism, the change needs to be considered and the shaft mechanism must be matched. The bending avoids the inability to cooperate with each other due to the turning state of the rotating shaft and the flexible screen, thereby causing damage to the flexible screen.

詳細而言，請再參考圖2，其中第三連動件141固定於第一轉軸111而彼此同步旋轉，第四連動件142固定於第二轉軸112而彼此同步旋轉。如圖2所示，藉由第一轉軸111與第二轉軸112所具備的削平狀軸體以分別對應第三連動件141、第四連動件142的削平狀開孔，而能順利使對應的構件產生以X軸的樞轉運動。在此，第一轉軸111具有中心軸X1，第二轉軸112具有中心軸X2。In detail, please refer to FIG. 2 again, in which the third link 141 is fixed to the first rotating shaft 111 and rotates synchronously with each other, and the fourth link 142 is fixed to the second rotating shaft 112 to rotate synchronously with each other. As shown in Figure 2, the flattened shafts of the first rotating shaft 111 and the second rotating shaft 112 correspond to the flattened openings of the third link 141 and the fourth link 142, respectively, so that the corresponding The component produces a pivotal movement in the X axis. Here, the first rotating shaft 111 has a central axis X1, and the second rotating shaft 112 has a central axis X2.

再者，轉軸結構100還包括固定架150，其大致呈「工」字型而具有中央結構以及沿X軸連接在中央結構之相對兩端的兩個隔板。第一轉軸111、第二轉軸112、第三轉軸113與第四轉軸114分別穿設於固定架150的四個固定位置，以達到前述彼此平行且具固定相對距離的狀態，其中第一轉軸111、第三轉軸113、第一連動件131、第一支架121與第三連動件141位於固定架150的一側，而第二轉軸112、第四轉軸114、第二連動件132、第二支架122與第四連動件142則位於固定架150的另一側，且與前述構件組（第一轉軸111、第三轉軸113、第一連動件131、第一支架121與第三連動件141）隔著固定架150的中央結構而相對。Furthermore, the rotating shaft structure 100 further includes a fixing frame 150, which is roughly in the shape of an "I" and has a central structure and two partitions connected at opposite ends of the central structure along the X axis. The first rotating shaft 111, the second rotating shaft 112, the third rotating shaft 113, and the fourth rotating shaft 114 respectively pass through the four fixed positions of the fixing frame 150 to achieve the aforementioned state of being parallel to each other and having a fixed relative distance, wherein the first rotating shaft 111 , The third shaft 113, the first link 131, the first bracket 121 and the third link 141 are located on one side of the fixed frame 150, and the second shaft 112, the fourth shaft 114, the second link 132, the second bracket 122 and the fourth link 142 are located on the other side of the fixing frame 150, and are combined with the aforementioned components (the first shaft 111, the third shaft 113, the first link 131, the first bracket 121, and the third link 141) They face each other across the central structure of the fixing frame 150.

Sections H1 and H2 are opposite to each other with one of the partitions interposed, and sections H1 and H3 are opposite to each other with the other partition. Similarly, the second rotating shaft 112 extends along the X-axis and is divided into sections H4, H5, and H6, and its configuration is the same as the first rotating shaft 111, which will not be repeated here.

此外，轉軸結構100還包括連動組件170與扭力組件160，其中連動組件170連接於第一轉軸111與第二轉軸112之間以同步旋轉第一轉軸111與第二轉軸112，後續將有進一步描述。扭力組件160連接於第一轉軸111與第二轉軸112之間，且扭力組件160與連動組件170沿X軸而位於第一轉軸111與第二轉軸112的相對兩端。如圖2所示，連動組件170設置在第一轉軸111與第二轉軸112的區段H3、H6，而扭力組件160設置在第一轉軸111與第二轉軸112的區段H2、H5。在此，扭力組件160包括限制套筒161與限制塊162，其中限制套筒161套設於限制塊162之外，而第一轉軸111與第二轉軸112的區段H2、H5被以夾持抵接的方式限制在限制套筒161與限制塊162之間，而據以產生摩擦力以作為第一轉軸111與第二轉軸112在進行樞轉運動時所需的扭力。In addition, the rotating shaft structure 100 further includes a linkage assembly 170 and a torsion assembly 160, wherein the linkage assembly 170 is connected between the first rotating shaft 111 and the second rotating shaft 112 to synchronously rotate the first rotating shaft 111 and the second rotating shaft 112, which will be further described later . The torsion component 160 is connected between the first rotation shaft 111 and the second rotation shaft 112, and the torsion component 160 and the linkage component 170 are located at opposite ends of the first rotation shaft 111 and the second rotation shaft 112 along the X axis. As shown in FIG. 2, the linkage assembly 170 is disposed in the sections H3 and H6 of the first rotating shaft 111 and the second rotating shaft 112, and the torsion component 160 is disposed in the sections H2 and H5 of the first rotating shaft 111 and the second rotating shaft 112. Here, the torsion component 160 includes a limiting sleeve 161 and a limiting block 162, wherein the limiting sleeve 161 is sleeved outside the limiting block 162, and the sections H2, H5 of the first rotating shaft 111 and the second rotating shaft 112 are clamped The abutment is restricted between the restricting sleeve 161 and the restricting block 162, and the friction force is generated accordingly as the torsion force required for the pivotal movement of the first rotating shaft 111 and the second rotating shaft 112.

圖3A至圖3C以剖切視角繪示圖1B的轉軸結構於不同狀態的示意圖。請先參考圖1B、圖2與圖3A，經由上述構件的樞接或連接關係，而使第一轉軸111、第三轉軸113、第一連動件131、第一支架121與第三連動件141構成第一連桿組LK1，而第二轉軸112、第四轉軸114、第二連動件132、第二支架122與第四連動件142構成第二連桿組LK2。轉軸結構100即是以所述第一連桿組LK1與第二連桿組LK2完成所需的樞轉動作。3A to 3C show schematic diagrams of the rotating shaft structure of FIG. 1B in different states from a cut-away perspective. Please refer to FIG. 1B, FIG. 2 and FIG. 3A. Through the pivotal connection or connection of the above-mentioned components, the first shaft 111, the third shaft 113, the first link 131, the first bracket 121, and the third link 141 The first link group LK1 is formed, and the second shaft 112, the fourth shaft 114, the second link 132, the second bracket 122, and the fourth link 142 form the second link set LK2. The rotating shaft structure 100 uses the first link group LK1 and the second link group LK2 to complete the required pivoting action.

請同時參考圖3A至圖3C，所示過程即是轉軸結構100從展開狀態逐漸轉換至閉闔（折疊）狀態，也相當於折疊式電子裝置10從圖1所示的展開狀態而轉換至第一機體200與第二機體300相互閉闔（折疊）的狀態。從圖3A至圖3C的過程中能清楚得知，正因轉軸結構100形成彼此呈鏡像對稱機構的第一連桿組LK1與第二連桿組LK2，故第一支架121與第二支架122會在所示的樞轉閉闔的過程（圖3A至圖3C）中逐漸遠離，而讓可撓螢幕400隨著第一機體200與第二機體300樞轉閉闔而呈現彎折時，所形成的彎折能被容納在第一支架121與第二支架122相對遠離所形成的空間（如圖3C所示）。反過來說，請參考圖3C至圖3A的過程，當第一支架121與第二支架122相對樞轉展開（也相當於第一機體200與第二機體300相對樞轉展開），則第一支架121與第二支架122會相互移近直至如圖3A所示維持在一平面上（所述平面平行於X-Y平面），進而得以順利地支撐呈攤平狀態的可撓螢幕400。Please refer to FIGS. 3A to 3C at the same time. The process shown is that the hinge structure 100 gradually transitions from the unfolded state to the closed (folded) state, which is equivalent to the foldable electronic device 10 transitioning from the unfolded state shown in FIG. The first body 200 and the second body 300 are closed (folded) with each other.
